Description

[Detailed description of the invention] This invention relates to a fitting structure between a watch case (hereinafter referred to as the case) and a band.

FIG. 1 is an assembled cross-sectional view of the conventional structure, in which the fixing member 13 is fixed to the back surface 121 of the band, the band tip 122 is abutted against the band mounting rising surface 112 of the case, and the back surface 121 of the band on both sides of the fixing member is fixed to the back surface 121 of the band.
The bent end portion 131 of the fixing member which has been bent and formed is abutted against the upper surface 114 and is abutted against the back surface 111 of the body, and the fixing claw wedge portion 141 is inserted into the gap between the spring bar 15 previously attached to the bottom 113 and the spring bar facing surface 132 of the fixing member.
The case and band fit together with a wedge effect.

In this conventional structure, the fixed claw wedge part 141 is only pressed between the spring bar opposing surface 132 and the spring bar 15, so if a force from an unspecified direction is applied to the fitting part between the case and the band, the fixed claw wedge part 141 The band would often fall out of the clamped state, causing the case and band to become unfitted and separate.

This idea is intended to solve the above-mentioned problem.

This invention will be described in detail below based on embodiments shown in the drawings.

FIG. 2 is an assembled sectional view showing this invention.

This device is designed to provide the fixed claw wedge part 141 from the assembled state.
The basic operation is the same as the conventional structure described above, and the structure added to prevent the fixed claw wedge portion 141 from falling off will be described in detail.

FIG. 3 is an enlarged perspective view showing the fixing claw 14 of this invention, which has portions on one side that protrude toward the outside, and a wedge portion 141 on the other side that approaches this. A dowel 543 is provided, and the intermediate portion has a bent portion forming a substantially V-shape on the inside to hold the spring bar 15. FIG. 4 is an enlarged perspective view showing the fixing member 13 of this invention, in which a portion having a U-shaped inner surface into which the outwardly protruding portion of the fixing claw 14 is accommodated is juxtaposed on one side. Further, the middle part is bent, and the bent part has a slotted window 53 into which the slotted dowel 543 of the fixed claw 14 is inserted.
4 is provided. The bent upstanding portion serves as a spring bar facing surface 132, and is further bent to form a fixing member tip 131. FIG. 5 is a partially cross-sectional perspective view of FIG. 2 seen from the back, and the case 11 includes a trunk back surface 111 that engages with the fixing member tip 131, and a band rising surface 1 that engages with the band.
12, and a pair of 〓113 holding the spring rod 15.
is provided. Band tip 12 of band 12
2 is attached to the upper surface of the case without any gap, and the back surface 121 of the band is placed on the upper surface 114 of the aforementioned 113. The fixing member 13 fixed to the back side of the band has a fixing member tip 131 that passes between the case side and the top from the top.
1, insert the fixing claw wedge part 141 between the spring bar 15 previously attached to the spring bar 113 and the spring bar opposing surface 132 of the fixing member 13, and insert the fixing claw wedge part 141 into the bite window 534 of the fixing member 13 that forms a concave part. The biting dowel 543 of the fixed claw 14 forming the part is inserted so that the two pieces bite together.

This invention has the remarkable effect of completely eliminating the phenomenon of the fixed claw wedge falling off from the clamped state by the dowel provided at the tip of the fixed claw wedge.

Claims (1)

[Scope of utility model registration request] Fix the fixing member to the watch case on the back of the band, place the back of the band on both sides of the fixing member on the top surface of the watch case, put the tip of the band against the side of the watch case, and place the rising part of the fixing member. The other end of the fixing claw has its tip abutted against the back of the body of the watch case, and a gap is created between the spring bar installed in advance in the bottom hole of the watch case and the upright part of the fixing member, and one end is fitted into the fixing member. In the fitting structure in which the watch case and the band are fitted by inserting the watch case and the band into the gap, the upright part of the fixing member bends and rises from the middle part fixed to the back surface of the band, and Fitting of a watch case and a band, characterized in that a bite window is formed, and the fixing claw is provided with a bite dowel at its tip and engages with the bite window. structure.
